摘要： System for predicting the remaining useful life of LED signaling lights comprises:
- one device (10) comprising a plurality of light-sensitive sensors (17)and arranged to capture one image of a railway signaling light (3) including a first LED lamp (4) emitting a light having a first color;
- one or more electronic processing units configured:
- to measure the actual intensity distributed over the plurality of light-sensitive sensors of said light; and then
- to calculate a future degradation rate of said first LED lamp (4) based on the measured actual intensity, and on one or more of: a reference intensity for said first LED lamp (4); an accumulated time of operation carried out by said first LED lamp (4), recorded data for said first LED lamp (4) indicative of previously measured intensity(ies).
